I saw somebody wondering why this was breaking the app wifi connection. This is a complete shot in the dark here, although it's a fairly educated one. Most wifi-using apps will keep track of the date and time independently, on their own servers, and check that against the time and date registered on your device. Now, if you're off by a couple hours, it'll most likely assume that you're in a different time zone. Off by a few years, then there probably either isn't code to handle that exception, or it blocks your out for security reasons. I'm guessing the flip between those two is different for every app. As for how to fix it in the future, perhaps Samsung should add a server time/date sync feature *shrugs* Mostly guesses in here, but it's more of an attempt at an answer to that question than I've seen so far. If anyone can confirm or correct this, feel free.
